Streaming Mixed Reality view compositor (mrvc) video to PC's C++ application

Hello,
I am new to Holographic and .net/UWP technologies. My goal is to read frames of hololens PV camera in real time(best 30fps) on Windows PC with Windows 10. The device portal and RESTful API have a big delay so I can not use them.

HoloLensCompanionKit's MixedRemoteViewCompositor project seems to be good for me and I can watch the composited video in real time, however I got the sample viewer code on the receiver side in C# not in C++, while I do not know a correct order to register MixedRemoteViewCompositor.dll on PC side even I found the C++ API RegisterSchemeHandler(). I tried to register the dll manually or in program, and also had some effort in regedit for registering the dll then let a general windows media player to understand the stream, but no success. If there is any one can point to a C++ video viewer code that can understand mrvc streaming on PC side, or instruct on steps of how to register a custom video handler dll for Windows Media Foundation, that will be highly appreciated.

Thanks,
Steve
